Pharma Semiconductor Fabric Engineering

This textbook provides a thorough and accessible treatment of semiconductor lasers from a design and engineering perspective. It includes both the physics of devices as well as the engineering, designing, and testing of practical lasers. The material is presented clearly with many examples provided. Readers of the book will come to understand the finer aspects of the theory, design, fabrication, and test of these devices and have an excellent background for further study of optoelectronics.

This book is concerned with the fabrication, operation and performance of modern semiconductor devices, the term 'device' being used here to encompass both discrete devices such as transistors and integrated circuits. The material presented has developed from a series of lectures given to students of electronics in the School of Electronic Engineering and Computer Science at Kingston Polytechnic over the past few years.

This textbook provides an in-depth treatment of the physics of power semiconductor devices that are commonly used by the power electronics industry. Drawing upon decades of industry and teaching experience and using numerous examples and illustrative applications, the author discusses in detail the various device performance attributes that allow practicing engineers to develop energy-efficient products. Coverage includes all types of power rectifiers and transistors and analytical models for explaining the operation of all power semiconductor devices are developed and demonstrated in each section of the book.

Semiconductor Device Physics and Design provides a fresh and unique teaching tool. Over the last decade device performances are driven by new materials, scaling, heterostructures and new device concepts. Semiconductor devices have mostly relied on Si but increasingly GaAs, InGaAs and heterostructures made from Si/SiGe, GaAs/AlGaAs etc have become important.

Preface for the second edition Chaos research in laser physics, especially in semiconductor lasers, has - veloped further even after completion of the ?rst edition of this book in the late summer of 2004, and it is still growing rapidly. For example, various forms of chaotic dynamics have been applied in newly developed semic- ductor lasers,such as in vertical-cavitysurface-emitting semiconductor lasers and broad-area semiconductor lasers. Chaotic dynamics plays an important role in these new lasers, even for their solitary oscillations, and control of the dynamics is currently an important issue for practical applications. - other signi?cant advance has been made in the area of chaotic optical secure communications. Chaotic secure communications using existing public opt- al communications links have been tested, and successful results have been obtained. In this second edition, I have ?lled in the gaps in the explanation of chaotic laser dynamics in the previous edition, and I have also added s- eral important topics that have been developed recently. In particular, a new chapter on laser stabilizations has been added, and a number of misprints in the ?rst edition have been corrected. I believe this book will be of interest not only to researchers in the ?eld of laser chaos, but also to those working in nonlinear science and technology. Hamamatsu, Spring 2007 Junji Ohtsubo Preface The aim of this book is the description of the state of the art of chaos research in semiconductor lasers and their applications, and the future perspective of this feld.
